UContentBrowserAliasDataSource

A companion to the ContentBrowserAssetDataSource which can display assets in folders other than their actual folder.

API > API/Plugins > API/Plugins/ContentBrowserAliasDataSource

A companion to the ContentBrowserAssetDataSource which can display assets in folders other than their actual folder. Aliases mimic their source asset as closely as possible, including editing, saving, thumbnails, and more. Some behavior is restricted such as moving or deleting an alias item.

Aliases can either be created automatically by tagging the asset with the value defined by AliasTagName and giving it a comma-separated list of aliases, or manually managed by calling AddAlias and RemoveAlias. ReconcileAliasesForAsset is provided as a helper function to automatically update new/removed aliases for an existing asset.
